great changes have taken place in the world with the help of science. in the past, life was nasty, brutish and short. it is hard to imagine how our forefathers could do without so many conveniences that modern science brings about. back then, only a small group of people enjoyed the very few comforts. but the majority of people didn’t even have sufficient food, let along their privilege to be educated. anyway, it is science that changes the world and makes people’s life better and better, although it also leads to some bad aspects at the same time.
